Can I get some input on loads for the 280 Express Remington. I worked out one for the Nosler 140 gr partition but the data I was originally using came from the 'net and showed 53.5 grains of IMR4350 as max. This was a poor load for grouping and I ended up with 55.5 grains of IMR4350 in a Win model 70 featherweight with 22 inch barrel. No signs of pressure and it shot .5 inch group at 100 yards. My old Hornady manual (3rd edition)says 57 grains of IMR4350 is max but this is obviously higher than modern books. I have another 280 in Remington 700 that I would like to work a load for, but rather than burn some more lead and powder unnecessarily I figure there are enough handloaders here to get more information.
